Best bet is to get the original threaded top post Bosch condensers. You should be able to locate them elsewhere for a little cheaper than what Wildfire gets. I would not use the MFG supply condensers. True they may work but why use them when the right parts are readily available. Same goes for the points. A few bucks saved is just not worth it. With the correct parts you reduce you chance for engine failure and problems. Buy the condenser install tools and flywheel puller to make the job easier.

This is an airplane guys not a lawnmower. If your lawnmower quits it isn't such a big deal. When an engine goes silent in a Lazair it can be a big problem. This is especially true when you are low-time. Go to great lengths to learn how to do this stuff right and you will be rewarded with many hours of trouble free running.

Early supplied 185's had solder top condensers. Later supplied 185s had condensers with a threaded top post, nut, lock washer. Later supplied points also are supplied with an eyelet that goes to the condenser. What this means is "No Soldered Connection at the condenser". The manufacturers supply 01-035 Sachs/Bosch condensers are "solder top" condensers. You choose ! I'd call Wildfire and be done with this even if it meant a few bucks more. Of course you could throw the old crusty condensers back in. That would save a few bucks but give you more to think about when you out flying. Pros and cons. You know.

There have been some instances where operators have been using 50 to I gas/oil ratio mixes for the Rotax 185cc engine. These engines are used on the Lazair Ultralight Aircraft. This is not advisable. In the original configuration the factory recommended a 25 to I mixture.

However in the Ultralight configuration a 30/35 to I is recommended - break-in and up to 10 hours of operation use a 30 to I mix ratio. After 10 hours a 35 to I is fine. A high quality petroleum base two-cycle oil is recommended.

NOTE using the larger Rotax engine oil mix ratio of 50 to I can and usually does lead to early crankshaft seal failure. Leaks at these areas can lead to lean fuel mixtures causing engine damage, and leaks at the mag side can result in oil on the points thus causing an engine failure.
